Optical Sensors - Photointerrupters - Slot Type - Transistor Output

OPB815W is a type of optocoupler manufactured by Optek Technology Inc. An optocoupler is a form of electromechanical switch that uses light to control a circuit. It has two components: a photodetector to detect light and a power switch for controlling current. OPB815W is part of the Slot Type Transistor Output family of optocouplers, meaning that it is designed for use in digital and analog circuits that require a continuous light signal to control switch states. The optocoupler consists of a plastic housing, an infrared LED, and a phototransistor. The LED has an intensity of 2 mA while its peak wavelength is 940nm. The phototransistor has a collector current of 1.7 mA and a collector-emitter voltage of 25V. The optocoupler is designed to interface with signal levels in the range of 3.3 to 30 V.The OPB815W is designed to be used in a range of applications, including as digital control devices, contactors, and relays. It is also commonly used in distance sensing applications, such as motion detectors and robotic systems. The optocoupler\'s advantage is that it can provide a signal between two separate circuits that is not affected by noise or capacitive loading. This makes it a suitable choice for accuracy-sensitive applications where high-frequency signals need to be accurately transmitted.To use the OPB815W, the LED is connected to one side of the circuit while the phototransistor is connected to the other. When the LED is illuminated, the phototransistor switches on, allowing current to flow through the circuit. This type of optocoupler is typically used in conjunction with a driver circuit such as a transistor or a logic gate that can provide more current or a more accurate switching action than the optocoupler alone.In the off state the OPB815W will turn off quickly and accurately, making it suitable for applications requiring a precise signal for controlling switching. The optocoupler is also designed to protect against over-current conditions, and has a response time of 300ns. Its optical slot size is 0.8mm, allowing the user to create signals from shorter distances. The OPB815W is an efficient and reliable way to control signals across circuits and provides a secure connection that will keep signals free from noise and interference. It is ideal for applications requiring a switching action that responds quickly and accurately, and can be used in any circuit with a voltage range of 3.3 to 30 V.
